1258 \`configure' configures this package to adapt to many kinds of systems.

1260 Usage: $0 [OPTION]... [VAR=VALUE]...
1261
1262 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1263 VAR=VALUE.  See below for descriptions of some of the useful variables.
1264
1265 Defaults for the options are specified in brackets.
1266
1267 Configuration:
1268   -h, --help              display this help and exit
1269       --help=short        display options specific to this package
1270       --help=recursive    display the short help of all the included packages
1271   -V, --version           display version information and exit
1272   -q, --quiet, --silent   do not print \`checking ...' messages
1273       --cache-file=FILE   cache test results in FILE [disabled]
1274   -C, --config-cache      alias for \`--cache-file=config.cache'
1275   -n, --no-create         do not create output files
1276       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1277
1278 Installation directories:
1279   --prefix=PREFIX         install architecture-independent files in PREFIX
1280                           [$ac_default_prefix]
1281   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1282                           [PREFIX]
1283
1284 By default, \`make install' will install all the files in
1285 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1286 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1287 for instance \`--prefix=\$HOME'.
1288
1289 For better control, use the options below.

1342   --with-build-libsubdir=DIR  Directory where to find libraries for build system
1343   --with-toolexeclibdir=DIR
1344                           install libraries built with a cross compiler within

1350 Some influential environment variables:
1351   CC          C compiler command
1352   CFLAGS      C compiler flags
1353   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1354               nonstandard directory <lib dir>
1355   LIBS        libraries to pass to the linker, e.g. -l<library>
1356   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1357               you have headers in a nonstandard directory <include dir>
1358   CPP         C preprocessor
1359
1360 Use these variables to override the choices made by `configure' or to help
1361 it to find libraries and programs with nonstandard names/locations.
